The Patek Philippe reference 5147 is a refined and highly distinctive Calatrava, combining the timeless elegance of the collection with the practical sophistication of an Annual Calendar complication. Introduced in the mid-2000s, the 5147 is powered by the automatic Calibre 324 S IRM QA LU, featuring Patek Philippe's patented Annual Calendar, which automatically distinguishes between 30 and 31-day months and requires correction only once each year at the end of February. Its beautifully balanced dial displays the day, date and month through three apertures, complemented by a power reserve indicator, moon phase and subsidiary seconds, creating a harmonious and highly legible layout.

Produced exclusively in white gold, the reference 5147 is distinguished by its elegant Calatrava case, applied Breguet numerals and finely detailed guilloché centre dial, giving the watch a distinctly classical character. Combining everyday practicality with traditional craftsmanship and refined aesthetics, the 5147 has become one of Patek Philippe's most admired Annual Calendar references, appreciated by collectors for its elegant proportions, mechanical sophistication and understated exclusivity.
